System debug and trace system and method, and applications thereof |
摘要 |
An embedded system or system on chip (SoC) includes a secure JTAG system and method to provide secure on-chip control, capture, and export of on chip information in an embedded environment to a probe. In one embodiment, the system comprises encryption logic associated with a JTAG subsystem and decryption logic in the probe for encrypted JTAG read traffic. Inverted encryption/decryption logic provides bi-directional encryption and decryption of JTAG traffic. Encrypted information includes both authentication of valid probe/target interface and encryption of debug data. |
